Details of the cell, electrodes, and electrolyte can be found on the internet, this only deals with the electroniv side of things. This came about when the circuits given on the internet on other sites, seemed to be inadequate for the task.
The PCB built up (without the driver transistors) is R455.00 (SAR) Individual quotes can be given for the type of driver transistor stages needed. (Amp capacity, power rating etc)
